    摘要: By using parallax compensation which performs prediction by using parallax between video images, the video images are encoded as a single video image. Reference parallax for a target image to be encoded is set, wherein the reference parallax is estimated using a reference image; area division in an image frame is set; parallax displacement for each divided area is set, wherein the parallax displacement is the difference between the reference parallax and parallax for the parallax compensation; data of the area division is encoded; and data for indicating the parallax displacement is encoded. During decoding, reference parallax for a target image to be decoded is set, wherein it is estimated using a reference image; data for indicating area division, which is included in encoded data, is decoded; and data of parallax displacement, which is included in the encoded data, is decoded for each area indicated by the area division data.

    摘要: The disclosed multi-view image coding/decoding device first obtains depth information for an object photographed in an area subject to processing. Next, a group of pixels in an already-coded (decoded) area which is adjacent to the area subject to processing and in which the same object as in the area subject to processing has been photographed is determined using the depth information and set as a sample pixel group. Then, a view synthesis image is generated for the pixels included in the sample pixel group and the area subject to processing. Next, correction parameters to correct illumination and color mismatches in the sample pixel group are estimated from the view synthesis image and the decoded image. A predicted image is then generated by correcting the view synthesis image relative to the area subject to processing using the estimated correction parameters.

    摘要: A video encoding apparatus used in encoding of a multi-viewpoint image. The apparatus generates a synthetic image for a camera used for obtaining an encoding target image, by using an already-encoded reference camera image having a viewpoint different from the viewpoint of the camera used for obtaining the encoding target image, and disparity information between the reference camera image and the encoding target image, thereby encoding the encoding target image. A predicted image for a differential image between an input image of an encoding target area to be encoded and the synthetic image generated therefor is generated, and a predicted image for the encoding target area, which is represented by the sum of the predicted differential image and the synthetic image for the encoding target area, is generated. A prediction residual represented by a difference between the predicted image for the encoding target area and the encoding target image of the encoding target area is encoded.

    摘要: An image generation method for generating image information of a color signal Y of an image A by using a color signal X of image A, and color signal X and color signal Y of an image B. The presence or absence of a point in color signal X of image B corresponding to each pixel position of color signal X of image A, and the position of the relevant corresponding point are estimated. To each estimated pixel position in color signal Y of image A, image information of the corresponding position in the second color signal Y of image B is assigned. Color signal Y at a pixel position in image A for which it is estimated that there is no corresponding point is generated by using the image information of color signal Y assigned to pixels having a corresponding point.

    摘要: An image generation method for generating image information of an image C by using an image A and an image B having a resolution higher than that of image A. Image C having the same resolution as image B is generated by enlarging image A; presence or absence of a point in image B corresponding to each pixel position of image C and the position of the relevant corresponding point are estimated; and to each pixel position in image C for which it is estimated that there is a corresponding point, image information of the corresponding position in image B is assigned. It is possible to generate image information at each pixel position in image C for which it is estimated in the corresponding point estimation that there is no corresponding point, by using the image information assigned according to an estimation result that there is a corresponding point.
